The evidence is clear that since on a levelized-cost basis, solar and wind power generation are now competitive with fossil fuels. But since the supply of these renewable resources is variable and intermittent, unlike traditional power plants.
The cost to consumers of using flat retail pricing instead of dynamic, marginal-cost pricing costs them more, but you seem to have an agenda that is opposed to promoting less fossil fuel burning so doubt I can convince you of anything.
